"Sorry, Wrong Era" is the 2nd episode Season 2 of The Adventures of Jimmy Neutron: Boy Genius.
Jimmy invents a small time remote. When he teases Cindy and Libby with his invention, Hugh asks to use it. When Hugh decides to go back 2 minutes, he types 2-0-0 , and accidentally sends Jimmy, Carl, and Sheen 200,000,000 years in the past. Jimmy, Carl, and Sheen decide to make an invention to go back to their time. A T-Rex attacks, but they manage to hide under a giant mushroom, in the meantime Carl finds a Leptictidium, and names it Leppy. A pterodactyl grabs Sheen and takes him back to it's nest and there are two young pterodactyls.
Back in the present, Hugh uses Jimmy's invention to annoy the people of Retroville. He goes to the Candy Bar, and annoys Sam and all the customers by re-eating ice cream for hours, and drinking Purple Flurp and burping all day. He signs up for parachute school, but annoys everybody by not using a parachute.
Jimmy and Carl and Leppy meanwhile have to finish up the invention, but they need diamonds. Carl looks up in the sky and sees a huge star, and he asks Jimmy what it is, and Jimmy says it's a huge asteroid coming down to Earth. Carl panics and Jimmy calms him down and says they have 4 hours until the asteroid hits Earth. Meanwhile, back at the nest Sheen is having fun with the pterodactyls and the mother comes back and she knew it was time to leave the nest, so she pushes them off the nest. Luckily, Sheen is rescued by the baby pterodactyls and they set off to find Jimmy, Carl, and Leppy.
After a long time of searching, Jimmy, Carl and Leppy finally find diamonds, but the T-Rex attacks, and it prepares to eat Carl and Leppy. Suddenly, Sheen appears and saves Carl and Leppy on the backs of the young pterodactyls. Jimmy remembers that the Tyrannosaurus' skull is harder than steel, so they use the Tyrannosaurus to crack the diamonds. Unfortunately, the asteroid has crashed into the Earth and it causes a big wall of fire spreading across the world to make the time of the Dino's end and causing the T-Rex to run. The time portal is all set and Jimmy, Carl, Sheen and Leppy jump in the time portal, and they make it back to their time, but Hugh is captured by an angry mob of citizens. First one is Sam, because he disgusted all of his customers by continuously re-consuming the same ice cream and purple flurp. Second one is Libby because he gave her and Cindy brain freeze earlier. Third one is a pregnant woman that was ready to give birth, but Hugh used the time machine to make her give birth repeatedly, before she starts to cry. Judy then tells everyone that she'll handle it. Hugh is punished by being locked up in a cage. Jimmy thinks that he altered the timeline, but Judy tells Jimmy not to worry, she had put Hugh in a cage to keep him out of trouble from annoying the townspeople of Retroville.
When Hugh is apologizing and Judy gives Jimmy back his invention knowing it that it belongs to him, Leppy pushes a random button on the remote and Jimmy goes back to the time of the beginning of the first part of the episode and Jimmy ends the episode surprised, saying to himself: "Whoa. Deja-vu.".
- Jimmy: Oh no! It can't be! Abundant mega flora, CO-2 heated atmosphere...LEAPIN' LEPTONS! My dad didn't send us back 2 minutes! HE SENT US BACK 200,000,000 YEARS!!!
- Sheen: What did you say!?
- Jimmy: HE SENT US BACK 200,000,000 YEARS!!!
- Sheen: Oh, that's what I thought you said.
- Jimmy: Without the Quantum Replay, we're trapped in the late Cretaceous period!
- Unseen carnivore: GGRRRRRRR!!!
- Carl: Jimmy, did they have mommies who make it go away in the late Cretaceous era?
- Sheen: Jimmy please! with our superior human intellect, we can easily outwit anything we run into!
- T. Rex: Rraarrrr!!
- Sheen: Go ahead Jimmy, outwit him. (Jimmy and Sheen run, while the T Rex begins sniffing at Carl)
- Sheen: Don't move Carl, it can't see you if you don't move (Carl strikes unusual pose).
- Jimmy: Sheen, that theory's been discredited!

- The title of this episode is like the Jurassic Park title design.
- This episode is similar to the short, Cookie Time.
- This episode takes place after Beach Party Mummy where Libby was improving to her current design even though that this and the previous episode were aired before that episode in US.
- When Jimmy said the theory that you have a stand still to a T-Rex was discredited, he meant that T-Rex has binocular vision and forward facing eyes and has very good eye sight, so they can still you if you don't move.
- When Jimmy said they went back two hundred million years to the late Cretaceous Era, it was actually 65 million years ago. It should've been the Triassic Era.
- When the Pterosaurs were on the ground they should have their fingers on their wings on the ground to support their weight.
- Sheen tried to calm Carl down by telling him a story. The next time he'll do this will be in Who's Your Mommy.
- If Leppy re-winded the whole episode, this episode probably didn't actually happen in the Jimmy Neutron universe because Leppy would have re-winded it again and again and again and the rest of these episodes after this one couldn't exist, or Jimmy could have changed the timeline resulting this episode never happening.
- Sheen says "Yabba Dabba Doo" in one scene, which is Fred Flintstone's catchphrase.
- The boys running up the three accompanied by Hanna-Barbera "running" sound effects and then sliding down the T. Rex's tail is also a reference to The Flintstones.
- If Jimmy, Carl and Sheen went back in time to prehistoric times and still be in Texas, they would have encountered a dallasaurs and a acrocanthosaurus, instead of a T-Rex and pteranodon.
- Leppy seems to have dinosaur feet and hands, when he is supposed to have kangaroo feet and rodent like hands.
- Sheen suggested to stand still so the dinosaurs will not see them, which is also a reference to Jurassic Park.
- Sheen almost ate guano in this episode.
- Leppy's species, Leptictidium, never lived alongside the dinosaurs. In real life, Leptictidium first appeared in the Eocene, around 50 million years ago. The non-avian dinosaurs have already been wiped out in the mass extinction 15 million years earlier.
